16mm Polycarbonate Triplewall Sheet Clear.

16mm Triple Wall Polycarbonate Roofing Sheets (Clear)
Our 16mm triple wall polycarbonate roofing sheets provide a strong, lightweight and highly durable solution for a wide range of roofing applications. Designed with a multi-wall internal structure, these sheets offer excellent insulation, strength and light transmission, making them ideal for both domestic and commercial projects.
These clear polycarbonate roofing sheets allow maximum natural light through while protecting against weather and UV exposure. The triple wall construction creates internal air pockets that improve thermal performance and structural rigidity compared to thinner sheets. :contentReference[oaicite:1]{index=1}
Triple Wall Construction – Strength and Insulation
16mm polycarbonate sheets feature a triple wall (multiwall) structure that enhances both strength and insulation. The internal layers form a honeycomb design that improves load-bearing capacity while helping to reduce heat transfer.
- Greater rigidity than 10mm sheets
- Improved insulation with multi-layer structure
- Suitable for wider spans between rafters
- Lightweight yet highly impact-resistant
This makes 16mm sheets one of the most popular choices for roofing projects where strength and performance are required. :contentReference[oaicite:2]{index=2}

Light Transmission and Clarity
Clear polycarbonate sheets allow high levels of natural light to pass through while diffusing direct sunlight. This creates a bright, usable space without the glare or heat build-up associated with glass.
